In a "religious parish corporation", five members comprise the Board of Directors. By virtue of their respective offices (ex-officio), the Bishop and the Vicar-General of the Diocese and the Pastor of the parish are automatic members of the corporation. The Bishop is the President, the Vicar-General is the Vice-President and the Pastor is the Secretary/Treasurer. In addition, two lay members of the parish - called "trustees" - are appointed by the ex-officio members in order to complete the Board.

Trustees serve the parish as advisors, overseers and councilors, entrusted with assisting the pastor in caring for the corporate well-being of the parish.
